I used amen cos it is used at the end of praying to God very much like 阿弥陀佛 in buddhism praying, ok?
halleluja means praise the Lord and often used in place of amen which means "so be it"
so either can be used in my case
appreciate your suggestion, but there is no need to keep putting words into my mouth
so GET OFF MY BACK (just kidding!!!!!!!!!)
BTW, your phrase "I am quite optimistic about the Political Reform it's going to be passed......." can also be written as "I am quite optimistic that the Political Reform is going to be passed......."
the latter just sounds better
